Network Address Translation
(NAT)
Nokia E65 supports STUN (Simple Traversal of UDP
Through NATs) servers for NAT (Network Address
Translation) traversal, for networks where you do not have
a public IP address. Even with STUN servers in use it is
possible that the connection will not work, as some types
of NATs still block the traffic.
The settings for NAT traversal can only be provisioned by
the service provider, for example over the air or via
download, but cannot be edited manually by the user.
Unlike the SIP settings and Internet call settings, the NAT
settings cannot be defined manually, and it is therefore
recommended to use provisioning offered by Internet call
service provider.
NAT
There are two types of network address translation.
The type often popularly called simply NAT (also named
Network Address Port Translation or NAPT) refers to
network address translation involving the mapping of port
numbers, allowing multiple machines to share a single IP
address. The other, technically simpler form - also called
NAT or basic NAT or static NAT - involves only address
